3．  100miles，平均时速60，前一小时以50的时速完成，问接下来的行程以什么平均速度完成。
   选75。
4．  150人参加关于两种饮料a和b的调研，其中喝a的喝b的加起来好像是142个人，一种都不喝的人是两种都喝的人的5倍，问都喝的人几个，答案好像是2。反正列两个方程式就解决问题了。

5．  510-700 （1）6个100元纸币；
   （2）6个1元纸币；答案是B，只有606元一种情况，差点错了。

6．  X!/（X-Y）!,问X=6时，使X!/（X-Y）!>20的y最小值。选项为5，4，3，2，1。答案是2。

7．
    上图的t应该是s, 0<s<8时，纵轴数值为T(s), 8<s<16时，纵轴数值为F(S). 问F(S)的最大值是否比T(S)的最大值大。
I）               F（s）<=T(s-8) （ 8<=s<=16）
II）            F(s) <=100  (  8<=s<=16)

答案是D

8．
    xy>z?

(1) xyz=1;

(2)xyz^2>1

答案是C。z>1,xy=1/z<1。

9．
    X的各个位数的和是170，Y是两位数，X=10^20－Y。问Y＝？答案47

10．             通过在一定时间内读取数值来确定温度，按照每分钟读取的数量除以7加上4，一分半读了147次，则温度为(147/1.5)/7+4=18

11．              A1=64, A2=66, A3=67, An=A(n-3)+8, 以下哪个数属于该数列：

A. 723
B. 885
C. 805
D. 796
E. 1025

选A，723=8*82+67

12．             成本y和x是一个线性方程式，y=ax+b,造10辆车时，成本1000元，造30辆车时，成本1500元，问40辆车时，成本多少。答案是1750。

RC：

有两篇是JJ里面提到的——“出版一个叫Gilman的人的作品的事情”和“科学家们喜欢用rRNA作为研究用工具”。前面提到了，就不多说了。rRNA的文章很长，专业生词多，但意思比较好理解，不要深究，了解文章概要，然后根据题目定位能做出来。

有一个忘记了。

有一个是关于企业污染的文章。

第一段，将企业污染的问题的概要。许多企业都觉得污染花费成本大而不太愿意去做，但其中提到了机会成本“opportunity cost”，讲企业不关注污染处理而造成的机会成本会比较大。有一题问“opportunity cost”的意思，比较简单。

第二段，引用了企业管理里面的另一个方面进行类比，好像是关于产品创新或改造的，问第二段对第一段的作用，我选的是类比（analogous）功能。

第三段，介绍了一些方式可以进行污染改造，或者是污染改造能给企业带来的一些益处。也出了一题，不难，理解了就能做出来。

1．说一个lake里面的某种鱼越来越少。
     所以政府就想从nearby lake弄这种鱼过来. 然后作者说这样不行吧,弄过来的量还没有每年村民养殖投放在lake里的多呢,鱼还是会越来越少的. 问weaken
答案是：村民养殖的鱼太容易被上钩被吊而生存能力更差。

2．一个国家的酒店业的在几年内税率没变化，住酒店的租金（酒店收入）总体也没变化，但国家在几年内的酒店业的总税收增加了。问为什么。

我选的是：高消费酒店更多地集中在了高税收地区。

3．讲一个消防员的经验比身体素质更重要，问能削弱答案中的哪一个。

我选的是，年青的消防员因为身强力壮不需要积累经验。（好像是这个意思，反正就只有一个选项是讲关于年青消防员的）

 AWA：

39. The following appeared in an Avia Airlines departmental memorandum.

“On average, 9 out of every 1,000 passengers who traveled on Avia Airlines last year filed a complaint about our baggage-handling procedures. This means that although some 1 percent of our passengers were unhappy with those procedures, the overwhelming majority were quite satisfied with them; thus it would appear that a review of the procedures is not important to our goal of maintaining or increasing the number of Avia’s passengers.”

 新1. The primary responsibility of citizens is to obey their nation's civil and criminal laws.
